Griggs is a sorcerer from the Vinheim Dragon School. He came to Lordran in search of his master, Big Hat Logan. He wears the Black Sorcerer Set, which in Vinheim indicates a secretive member of the Dragon School.
The player finds Griggs in a locked room at the bottom of the Undead Burg. After being rescued he returns to Firelink Shrine, however, if the Chosen Undead learns all the spells he has to teach, Griggs is later found hollow in Sen's Fortress, right where Logan was imprisoned.
